Exxon Mobil Corp., the largest U.S. oil company, said North America may be able to export 15 percent of its natural gas output and 5 percent of oil by 2040 as the region’s production surges and demand stalls.
North America probably will become a net energy exporter by about 2025, after importing 35 percent of its oil in 2010, Irving, Texas-based Exxon said in an energy outlook report released today. Asia Pacific countries may import almost 40 percent of their total energy needs by 2040 as demand increases.
“After decades of relatively flat production, output of oil and other liquid fuels in North America is projected to rise by about 40 percent from 2010 to 2040,” Exxon said in the report. Meanwhile, “overall U.S. energy consumption is expected to gradually plateau and then decline by about 5 percent from 2010 to 2040.”
Technological advances have helped tap oil and gas from shale-rock formations, as well as extracting it from oil sands and deep-water prospects in North America. Monthly U.S. oil production exceeded 7 million barrels a day in November, for the first time in 20 years. The International Energy Agency said in November the U.S. is poised to surpass Saudi Arabia as a crude producer in the next decade.
U.S. liquefied natural gas exports will stay below 10 billion cubic feet a day, Bill Colton, Exxon’s vice president for corporate strategic planning, said during a presentation on the outlook at Rice University in Houston.
Exxon assumes that at some point in the next 30 years governments around the world will begin putting a price on carbon emissions, Colton said. Exxon sees a possible price of $60 a ton of carbon dioxide emitted in the U.S. in 2030.
Under that circumstance, the price to burn coal to generate electricity jumps well above gas, which has about 50 percent fewer emissions, Colton said.
“Coal’s got a lot of environmental pushback, wind and solar are growing but they’re limited from a practical standpoint, nuclear is also limited from practical and political considerations,” he said. “That provides this huge opening for natural gas as sort of the fuel of choice for the future.”
More use of gas instead of coal and increased output from nuclear and renewable energy sources will reduce U.S. greenhouse-gas emissions, Exxon said. Carbon-dioxide emissions may drop more than 25 percent by 2040 to the lowest levels since the 1970s, the company said.
Exxon wants the U.S. government to revise its rules for blending ethanol into gasoline to cap the level at 10 percent of total gasoline consumption, Colton said.
Automobile manufacturers aren’t comfortable with ethanol making up more than 10 percent of fuel blend, he said. Government regulations are calling for the total amount of ethanol to be blended into gasoline this year to be greater than 10 percent of total expected gasoline demand.
“We call it the blend wall,” Colton said. “The problem is, when they set those mandates and they have them growing, I don’t think they realized demand for gasoline would be shrinking.
‘‘It’s just another reason why it’s difficult to make gasoline, and frankly it puts cost pressures on making gasoline,” he said. “So we think it’s in the general good to cap it at 10 percent, and even less would be a bonus for consumers.”
In December, Exxon released a broader report with its global energy outlook, boosting its long-term estimate for worldwide demand growth to 35 percent from 32 percent as expanding populations in Africa and India use more electricity.
